If you want to dine luxuriously, then the best choice will be restaurants Le Trianon and Mövenpick Restaurant.
It serves just gastronomic masterpieces. Plus the interiors of restaurants are also very elegant and are quite original. The interior of the Le Trianon restaurant is made in ampir style, the hall is decorated with ancient antique furniture and large curtains. Here serves Swiss, Alsatian and French cuisine.
For lovers of seafood- Les artistes. In this restaurant I advise you to try baked carp, which is characterized by the taste of fish, impregnated with exquisite spices.
If you prefer to eat not far from the lake, I can advise Le Maritime, a very picturesque restaurant, because the trapping can be enjoyed the surroundings of the lake and the city.
Some tables stand on the outdoor terrace, which is very romantic if you relax a couple.
A pear cake is considered very tasty among local cuisine.
Inexpensive dinner can be in the supermarket coor, where they sell inexpensive snacks and cooking. For people with a trimmed budget, it is just the perfect option.
The excellent location are bars and pubs where you can drink really delicious beer. For example, Löwengraben and Opus.
But the best is the beer of the local brewery Rathaus.
